Hi Jack, That’s interesting, well, based on Ruida settings at min power 20% and max power 80% I have listed below the test values sent from LightBurn (in ‘Line’ mode with min and max power the same) along with the corresponding power values I would expect the PWM signal to be delivering to the power supply - which I have confirmed to be correct on a scope. If you get the chance to check some of these other values from your system just to confirm what is happening for you I would appreciate it. And let me know the firmware version you are running.(Edit\>Get Controller Info). I’m running a RDC6442G with v8.07.70. The 80% reading will be interesting for you to check since the value we are both expecting is wildly different! Thanks. ![image](https://forum.lightburnsoftware.com/uploads/default/original/3X/a/2/a237f64c913d132f25bfe56974c0a5f42f2adead.png) Cut Settings % power Vs. Ruida actual output power % 0 = 20 10 = 26 (you reported 20% here?) 20 = 32 (are you expecting 20% here?) 30 = 38 (are you expecting 30% here?) 40 = 44 50 = 50 (you got 50% here but that is also what I was expecting 🙂 ) 60 = 56 70 = 62 (presume you get 70% here?) **80 = 68 (presume you get 80% here?)** 90 = 74 (you reported 80% here?) 100 = 80 --- _[View the full topic](https://forum.lightburnsoftware.com/t/ruida-min-and-max-power-rescales-actual-power-output/107903)._
